Prior to 0.152.0, cmd/otel-allocator TargetAllocator instances with targetAllocator.prometheusCR.enabled set to true preserve a selected ServiceMonitor endpoint's bearerTokenFile value as HTTPClientConfig.Authorization.CredentialsFile. A tenant who can create or update a ServiceMonitor matched by serviceMonitorSelector and serviceMonitorNamespaceSelector can point bearerTokenFile at a file in the Collector pod, including /var/run/secrets/kubernetes.io/serviceaccount/token, and direct scraping to a tenant-controlled endpoint. The Collector reads that file at scrape time and sends its contents as bearer authorization on every scrape interval. Exploitation also requires the Collector service-account token or another sensitive file to be mounted and the Collector to reach the chosen target. The DenyFSAccessThroughSMs control was absent, allowing disclosure of the Collector's service-account JWT or other mounted files, and resulting Kubernetes API impact is limited by the Collector service account's permissions. This issue is fixed in version 0.152.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-47701)\n\nAffected packages:\n\n- `github.com/open-telemetry/opentelemetry-operator < 0.152.0`\n\nPatched in:\n\n- `github.com/open-telemetry/opentelemetry-operator 0.152.0`\n\nSource: https://github.com/advisories/GHSA-cxh2-4639-vmc5\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat Advanced Cluster Management for Kubernetes 2 · no fix planned: Red Hat Advanced Cluster Management for Kubernetes 2 · updated 2026-09-14 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-47701.json)","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":42.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
